[SOLVED] Traffic graph not visible in Firefox

[StP]

Hi,

on Status->Traffic graph I can only see a textual representation of the current data, but no diagram.
OPNsense 15.1.9.2, Firefox 37.0.2
Any setting I have to activate?

Regards

@StP, is the Adobe SVGviewer installed?

No, as the hint text says "SVG-Viewer or Firefox 1.5 or later..."

Have you tried another browser to verify? It might be a security setting. We haven't had similar reports yet.

Internet Explorer 11 shows the graph.

It might be a security setting.

Well, this one is showing up fine. So in general displaying SVG works.

Maybe an AdBlocker or another plugin preventing the graph from showing up. I don't know how else to debug this if the graph does work in general...

I have AdBlock Plus installed, but deactivating it does not solve the problem.

Anything I can do to help?

o try loading  https://yourip/graph.php -- it should show an empty but visible graph.
o try upgrading to 15.1.10.1 (or at least try the live image)
o try disable all plugins, delete caches and cookies

Do you have a different user added or changed access permissions?

Ok, the culprit was Flashblock 1.5.18, a Firefox add-on that stops flash content from auto-playing.
As soon as this one is deactivated the traffic graph is visible.

Loading https://yourip/graph.php shows an empty graph even if the add-on is active.

I have now replaced Flashblock with NoScript and this seems to work fine.

No idea why a flashblocking software stops the graph display???

Thanks for your support

Glad to hear that. The blacklist patters are quite arbitrary and prone to false-positives like any good blocker or security product out there ;)
